How to Fix Loss Of Fingerprint Sensor Issue on any OnePlus Device

The below instructions are listed under separate sections for ease of understanding. Make sure to follow in the exact same sequence as mentioned. [All Credits for this guide go to XDA Senior Member antnyhills ]. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.

STEP 1: Install Android SDK

First and foremost, you will have to install the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one. So download it and then extract it to any convenient location on your PC. Doing so will give you the platform-tools folder, which will be used throughout this guide.

STEP 2: Backup Current Persist Partition

First and foremost, you need to backup your current persist.img. But since you are already facing fingerprint issues, wouldn’t this partition be already corrupted? Well, although it is broken, it still has all our working calibrations, including the all-important FingerPrint calibrations. So let’s proceed ahead and take a backup of the persist partition.

1. To begin with, connect your device to the PC via USB cable. Make sure USB Debugging is enabled.
2. Then head over to the platform-tools folder, type in CMD in the address bar, and hit Enter. This shall launch the Command Prompt window.
3. Type in the below command in this window to gain administrative privileges: adb shell su
4. You might get a prompt on your device, make sure to allow it.
5. Finally, execute the below command to take a backup of the persist partition: dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist.img
6. If the aforementioned command doesn’t work, then you could use the following command:
7. su -c dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/Download/persist.img

It is recommended you transfer this backup to your PC as your device will be formatted in the subsequent steps to fix the loss of fingerprint sensor issue on your OnePlus device.

STEP 3: Downgrade OnePlus via MSM Download Tool

You will now have to flash an older build of OxyegnOS on your OnePlus device using the MSM Download Tool. Here’s how it could be done:

1. To begin with, install the Qualcomm HS-USB QDLoader 9008 Drivers onto your PC.
2. Then download and install the MSM Download Tool on your PC corresponding to your device.
3. Now launch the tool, select Other in the Login prompt, and click Next. Credits: OnePlus Forum
4. Click on the Target button and select O2 for Internation Firmware, India for Indian, or EU for European Tool.
5. Connect one end of the USB cable to the PC. Then press and hold the Volume Up and Volume Down keys on your device and while doing so, connect the other end of the USB cable to your device.
6. Your device shall now boot to the EDL Mode and you may now let go of the pressed Volume buttons.
7. Finally, hit the Start button and wait for the flashing to complete.

STEP 4: Unlock OnePlus Bootloader

After downgrading via the MSM Download Tool, the device’s bootloader will be locked again. So unlock it using our guide: How to Unlock Bootloader on Any Android Device . Do keep in mind that doing so will wipe off all the data from your device, so take a backup beforehand. Once the bootloader stands unlocked, move over to the next step to fix the loss of fingerprint sensor issue on your OnePlus device.

STEP 5: Enable Factory Mode on OnePlus

1. To begin with, download a File Explorer that supports root (such as Solid Explorer).
2. Then launch the app and tap on the hamburger menu situated at the top left.
3. Select the Root directory and grant it the permission in the Magisk request that appears.
4. Now go to the below location: /mnt/vendor/persist/engineermode/
5. There you should find the engineermode_config file, open it using a text editor.
6. There you should find the following two lines: encrypt_app=true encrypt_adb=true
7. Change their values to false, so the above two lines should now be: encrypt_app=false encrypt_adb=false
8. Finally, save the changes and reboot your device and then proceed to the next step to fix the loss of fingerprint sensor issue on your OnePlus device.

STEP 6: Perform OnePlus Fingerprint Calibration

Now comes the interesting part. We will have to perform a fingerprint calibration but have to intentionally fail this test. Here’s how:

1. To begin with, bring up the phone dialer and type in the below code: *#808#
2. Then go to Device Debugging from the top menu bar > Fingerprint test > Fingerprint calibration test(Pure White – 90% Blue).
3. Finally, tap on the Start test button situated at the top. Now here are all the tests and what you need to do: First off is the Flash Rubber Sleeve Test 1. Tap on it and then immediately put your fingers over the sensors Next is the Black Rubber Sleeve Test. Tap on it and do not put your fingers over the sensors. The third one is the Positioning Circle Test. Tap on it and then immediately put your fingers over the sensors. The final one is the Stripe Rubber Sleeve Test. Tap on it and then immediately put your fingers over the sensors.
4. So black rubber is the only test in which you do not have to put your fingerprint over the sensors.

You should now get many red lines of errors indicating the failure of this test. If you only get one or two lines of error, then try again and reproduce more errors, as shown in the below image.

STEP 7: Extract Persist.Img

You will now have to extract the persist.img file, the file that we backed up in the second step. Yp could use the 7-ZIP software to extract this IMG file. Once extracted, you shall get quite a few folders. Copy the data and engineermode folders and transfer them to your device. Once done, proceed to the next step to fix the loss of fingerprint sensor issue on your OnePlus device.

STEP 8: Replace Old Data and Engineer Mode with New One

1. Launch the Solid Explorer app, go to the Data folder and delete the gf_persist.so file.
2. Once that is done, copy the data and engineermode folders that you had just transfer to your device from the Persist file.
3. Finally, paste these two folders in the below location: /mnt/vendor/persist/
4. You will now get a confirmation asking whether you want to keep the new folders or the old ones, select the New one.
5. Finally, reboot your device. Once it boots up, you may now set up your fingerprint without any issues (Settings > Security and Lock Screen > Fingerprint).

Pixel 6 Fingerprint Sensor Not Working: How to Fix

In this guide, we will show you various methods to fix the Pixel 6 fingerprint sensor not working issue. The latest offerings from the Silicon Valley giant have bought in a plethora of new goodies. Right out of the box, you will notice a completely revamped design, which was literally the need of the hour for this series. Then there are quite a few nifty camera tweaks as well which is generally along the expected lines for this lineup.

Apart from that, you will now also be getting three years of OS upgrades and five years of security patches. Moreover, the sixth iteration has welcomed an in-display fingerprint scanner, which is a first for any Pixel device. However, as opposed to other flagships that have straightaway opted for the 3D ultrasonic scanner, Google decided to stick with the old 2D optical scanner. And this isn’t proving to be the right decision.

A slew of complaints are getting accrued where users have voiced their concerns that the under-display fingerprint scanner isn’t working along the expected lines. Considering the money being spent on purchasing these flagships, and the issue gets all the more worrisome. Well, if you are also getting bugged with this issue, then fret not. In this guide, we will make you aware of various methods that shall help you fix the Pixel 6 fingerprint sensor not working issue.

How to Pixel 6 Fingerprint Sensor Not Working

Do note that there’s no universal fix as such. You will have to try out each of the below-mentioned workarounds and see which one works best in your favor. So keeping that in mind, let’s get started.

Add the Same Fingerprint Twice

An old trick out of the books, adding the fingerprint of the same finger twice or thrice will make the job of the scanner a little bit easier in reading those fine prints. So head over to Settings > Security and fill up two-three slots of fingerprints using the same finger. Then check out if it manages to fix the Pixel 6 fingerprint sensor not working issue.

Give it An Additonal Second

Optical under the hood fingerprints are a tad bit slower than the ultrasonic scanner. So bearing that fact in mind, consider giving an additional second to the scanner so that it is able to efficiently scan your prints.

Apply Optimal Pressure

While it isn’t documented anywhere as such, but these in-display fingerprints (especially the 2-D ones) work best when you apply the pressure in an increasing manner. However, the increase should be done gradually and lightly. So try it out and then see if it is able to fix the Pixel 6 fingerprint sensor not working issue.

Use Dry Hands

It’s no hidden secret that the scanner wouldn’t be able to read the fingerprints if your hands are wet. This is because the moisture would end up creating an additional layer between the scanner and your fingerprints, thereby preventing a successful scan. So make sure to remove such roadblocks before proceeding ahead.

Clean your Screen

Not only your hands but the screen should be cleaned as well, especially the bottom half of the screen where the scanner is located. Even the slightest of dust particles are enough to create hurdles in successful scans. So clean your screen via a cloth or fabric and then verify if the Pixel 6 fingerprint sensor not working issue has been fixed or not.

Use a compatible screen protector

Not all screen protectors are created equally! While they might cause any issues in the normal usage of the device, but they sure could cause conflict with the in-display fingerprint scanner. So if you ever plan to replace your Corning Gorilla Glass Victus protection with a third-party one, make sure to go for a tried and trusted name.

Re-Add Your Fingerprint

Since the optical scanner flashes a bright light underneath to read your fingerprints, it might not have been able to register your fine prints correctly during the setup process. So consider removing the registered fingerprint via Settings > Security and then perform a re-scan to re-add your fingerprints. Check if this gives out any favorable results or not.

Install Pending Updates

While the software upgrades might not necessarily add new features to your device, they surely optimize and improve the overall functioning of the OS as well as your device. Along the same lines, they also iron out all the bugs and issues. So make sure to download and install all pending updates via Settings > System > System Update and then verify if it ends up rectifying the issue or not.

Give AI some time!

Well, Artificial Intelligence does take some time to adapt and adjust, after all. So on continued usage of these scanners, they will ultimately learn and optimize themselves according to the use case scenario. So consider letting go of the initial hiccups for a better journey ahead!

Contact Google

If none of the aforementioned tweaks managed to work out in your favor, then you should consider contacting Google and then chalk out the best route forward. We aren’t still implying that it’s a hardware issue, it’s just that contacting the manufacture will give you a clearer picture.
